The Main Performance Test of New Digital Reactivity Meter
The measurement accuracy,continuity and stability of a newly developed high performance digital reactivity meter were tested in laboratory and zero power reactor The test results show that:The developed reactivity meter meets the requirements of technical index of reactivity meter development,and all the indexes are higher than the requirements of reactor physics experiment for the use of reactivity meter,and it is suitable for the measurement of reactivity in various reactor physical start-up experiment.
